Disaster in the making

A VIRUS that kills every one of its victims, by wiping out part of their immune system, has been accidentally created by an Australian research team. The virus, a modified mousepox, does not affect humans, but it is closely related to smallpox, raising fears that the technology could be used in biowarfare.

The discovery highlights a growing problem. How do you stop terrorists taking legitimate research and adapting it for their own nefarious purposes?

"But it's a good way to show how to alter smallpox to make it more virulent," says Ken Alibek, former second-in-command of the civilian branch of the Soviet germ-warfare programme.
